I bypassed the driver so only eight finals are being used. I took out the 3.3 pf Capacitor at the input so239 & put in a 15 pf. I have it in line with my icom. 30 pep on SSB now it does 325 watts peak. I listened to it & it sounds just like the radio does with amp off. Only thing seen is an increase on the s unit meter. Lovely amp after mod is complete. That driver is making it sound bad. Being the driver is gone you can drive it with the rated pep of one transistors. I don’t go over 40. Go on amazon & lookup My Sweety 50 amp 600 watt 12 volt power supply. It has all the protection you could ask for, adjustable voltage I set mine to 15 volts & @50 amps it runs this amp nicely. For $39 you can’t go wrong. It’s black in color.
